SYRINGE.

SPECIFICATION forming part of Letters Patent No. 397,060, dated January 29, 1889.

Application tiled September 25, 1885. Serial No. 178,131. (No model.)

To all '107mm it may concern:

Be it known that I, ALBERT M. KNAPP, ot the city ot Providence, in. the county of Providence, State of Rhode Island, have invented a new Syringe-lipe, of Awhich the lol lowing is a specification.

My invent-ion consists in an improved syringe-pipe, to be used in connection with a syringe for the purpose of making liquid applications to the internal surface of the'vagina and neck ot' the womb for the medical treatment of those parts.

The vagina lrests in rug or folds; consequently unless expanded a considerable portion of its surface is not reached by medicated liquids injected through the small. tubes now in general use. Through the operation of my improved device a degree of expansion is secured, exposing the whole vaginal surface and neck of the womb to the inliuence of medical washes, and also plugging the vaginal canal, thereby retaining the liquids in contact with the parts for a proper length ol' timea desirable object in the treatment.

In the accompanying' drawings,whieh.illustrate my invention, Figure l represents a side elevation ot` my improved device as itis when not in use, the expansible bulb being closed. Fig. 2 is a sectional view, the bulb being in the position assumed by it when in use. Fig. S is a detail view of the valve adapted to the end of the pipe.

To the free extremity of a syringe pipe, 71 or tube, quite close to the end l), is attached an expansible thin hollow bulb, a, the opposite sides of which are fastened air-tight to said tube or cylinder, which passes through said bulb and projects slightly beyond, as at b. The continuation ol' the canal or bore e through said tube 'is partially interrupted in that portion covered by said bulb and freely comuninicates with the interior of the saine, as shown by the arrows, Fig. 2. On the end of said tube, and in close proximity to said bulb, a valve, k, is attached, which olers a slight resistance to the passage of liquids forced into the opposite end, c. .llirough the means of the obstruction secured by this valve liquids injected into said tube must lill said expansible bulb to its t'ull capacity before pressure enough is brought to bear upon said valve to open the saine and give vent to the injected solutions. lhc expansion of said bulb a can also be accomplished in the following manner: In the end l) ci the said tube, Which extends just beyond said bulb, tine perforations are made. These holes are so small that the liquids forced into said tube cannot be discharged vwith equal rapidity; consequently they are forced into and continue to expand said bulb so long as the syringe is in operation.

The valve 7i' in ay be used with the lin e peri'orations in the pipe end, and in any event it acts to retard the flow of liuid through the pipe and to prevent its return after it has passed into the vaginal canal.

Operation: Connect the syringe-pipe with the syringe and insert into the vagina so that the said bulb occupies a position just within the vaginal orifice. Operate the syringe, and the solutions will pass through the said tube into the said bulb, tilli ng the saineto its greatest capacity, thus separating and expanding the walls ot' the vagina in the immediate vieinity. The liquids are then forced through said valve, or the said fine pcrtforations, into the vaginal canal. Sai d expand ed bulb plugs the vagina; consequently a quantity of the injected solutions is retained, occupying a space between the surl'ace ot' said expainled bulb and the mouth of the womb, dilating the vagina to a degree equal io the diameter ot' said bulb beli'ore any ol" the solution is discharged.

In the operation oli' the said device, owing to the expansion of said bulb, the instrument has a tendency to press inwardly against the womb. To prevent this, a guard is adjusted to said pipe between said bulb andthe point of connection with the Syri nge.

The instrument is removed from the vagina by disconnecting it from the syringe. The natural contraction ot' the parts soon discharges the contents of the said bulb, when it is easily displaced.

I am aware that it is old to use a flexible and expansible bulb combined with a vaginal syringe-pipe, and I do not claim this combination, broadly.

I claim as my invention and desire to secure by Letters Patent- Y l.
